winter prep....

[yaris2010RS]

okay, i know its early but i need to start preparing for winter. im not in a situation to make my car a sleeper (parked all winter) so i need to prepare to drive it in snow. currently its sitting on the ground with stock rims and tires.

my main question is what is better for the winter (if it matters at all), raise the coilovers all the way up or put the stock suspension back in the car?

my original thought was to just raise it up on the coilovers but after reading info about lowering kits and the pros and cons to springs vs. coilovers (if u lower ur car with springs and dont change shocks they will work at bottom end and wreck them), i was wondering if the same applied to the higher end of the coilover shocks.......

also i know a big thing too is to change to winter tires, i will see how the first snowfall goes and decide from there.

also how important is it to change to stock intake? i have also been considering that.

we have lots of time before winter becomes a reality so any input is appreciated.
